Aimsun is an integrated transport modelling software, developed and marketed by TSS - Transport Simulation Systems based in Barcelona, Spain.

Aimsun software is used by government agencies, municipalities, universities and consultants worldwide for traffic engineering, traffic simulation, transportation planning and emergency evacuation studies. It is used to improve road infrastructure, reduce emissions, cut congestion and design urban environments for vehicles and pedestrians.

The latest version - Aimsun 8.1 - was released in June 2015.

Aimsun has over 3,500 licensed users in 70 countries.[1] It is also used as a decision support system for real-time, simulation-based online traffic forecasting as Aimsun Online.
